Getting the filter profile wrong on a 4WD unit starves the valve body of fluid before the transmission ever gets a chance to shift cleanly, and a dried or cracked pan gasket turns a routine service into a comeback. This two-piece set addresses both points for 4L60E, 4L65E, and 4L70E automatic transmission units in 4WD configuration: one stepped filter sized for the raised pickup position found in 04-UP 4WD applications, and one cork bottom pan gasket for the TH700-R4 and 4L60E pan.The stepped filter is not interchangeable with the flat version. In 4WD applications from 04-UP, the filter seating surface sits higher in the pan, and a flat filter will not seat flush, leaving a gap that bypasses filtration. The stepped design seats correctly in that position.The cork pan gasket seals the bottom pan on TH700-R4 and 4L60E units. Cork compresses evenly against a machined surface and does not require sealant when the pan rail is in good condition, which keeps re-entry time short during a fluid service or inspection.This set contains exactly two parts: one stepped 4WD filter and one cork pan gasket. It does not include friction clutch packs, steel plates, sealing rings, thrust washers, bands, or any other internal components. If your job calls for those parts, they need to be sourced separately.Each box leaves the REMCO facility with a printed parts list so you can verify count before opening a single bag. REMCO has worked in automatic transmission parts since 1991, and every set is assembled by hand from individual components.Confirm the transmission code (4L60E, 4L65E, or 4L70E), the drive configuration (4WD), and the production year (97 or later for the gasket, 04 or later for the stepped filter) before placing the order. Addresses two of the most common fluid-path issues at once: a clogged or wrong-profile filter and a leaking bottom pan gasket, both covered in a single order. This set does NOT include friction discs, steel plates, sealing rings, bands, or any other rebuild components. Review your parts list before ordering to confirm this covers what your job needs. The stepped filter profile is specific to 4WD applications from 04-UP within the 4L60E 4L65E 4L70E family. Using a flat filter in this position restricts flow; the stepped design fits the pickup correctly. Contents: 1 stepped 4WD filter [04-UP] for 4L60E 4L65E, and 1 cork bottom pan gasket for TH700-R4 4L60E. Total weight: 1 lb. Parts list is included in the box. Before ordering, confirm your transmission code is 4L60E, 4L65E, or 4L70E, that the unit is 4WD, and that year is 97 or later. The stepped filter applies to 04-UP units only.
